At first glance, sunglasses may seem to prevent the sun from shining in your eyes. That's true, but the eye that looks at the world through the glass of sunglasses will not miss some of the other benefits this revolutionary invention offers. Apart from the fact that you do not have to lubricate the iris of your eye with a tanning cream, no one else will know where you are looking at too. And that is great in some cases. And guess what - sunglasses fit everybody!
